Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized for initiating, closing, pressure balancing, and discharging the input signal for differential pressure, pressure transmitters, and flow transmitters. This innovative valve group ensures effortless installation, maintenance, and online inspection of instruments, providing unparalleled convenience and reliability. The valve group can be de
i
vided into 2-valve groups, 3-valve groups, and 5-valve groups based on their functionality, and P type
(Flat type), T type, H type, and cylinder stop valve based on their structural design.
Integrated Valve Group
Assemble the transmitter and valve group in the factory, followed by comprehensive pressure and leakage testing. This method significantly reduces on-site installation efforts and prevents leakage stemming from transmitter installation.
Valve Group Features
· Safety Stop Pin
Crafted from stainless steel to ensure the valve seat remains secure within the valve body.
· Valve Body Design
Featuring an integrated structure, this design offers exceptional strength and reliability.
· Valve Seat Sealing
Employing hard sealing between stainless steel components for enhanced safety and reliability.
· Valve Core
The valve core components utilize a segmented structure, enhancing both the sealing performance and service life of the valve group. Additionally, the handle operation has been refined for improved usability.
· Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw, minimizing friction and bolstering sealing performance.
.
Structural Features
The valve groups are controlled by the stop valve, discharge valve, and balance valve. While valves with different functions vary in size and markings, they share common structural features.
·Flexible Mounting
Plate type, Flange straight mount, 1/2NPT joint, and pipeline connection.
· Structure Material
Crafted from high-quality materials: SUS316, SUS304, SUS321, HC-276, and more.
· Signal Cap
Featuring stop valve, balance valve,
and discharge capabilities,
these valves come in vibrant blue, green, and red signals, offering a fresh and natural appeal.
· Gland Packing
Available in PTFE and Graphite.
· Working Pressure
Designed for robust performance at 16MPa and 32MPa.
· Operating Temperature
Capable of withstanding temperatures from -40 to 150
ºC
(-40 to 302°F).
